Computing Estimators of Dantzig Selector type via Column and Constraint Generation

18 Aug 2019Rahul MazumderStephen WrightAndrew Zheng

We consider a class of linear-programming based estimators in reconstructing a sparse signal from linear measurements. Specific formulations of the reconstruction problem considered here include Dantzig selector, basis pursuit (for the case in which the measurements contain no errors), and the fused Dantzig selector (for the case in which the underlying signal is piecewise constant)...
